Heckler and Koch MR556 A4 | Rifle | 16.5” Barrel | 5.56/ .223 | 10 Rounds | Black | HK81000828

The HK MR556 A4 is the commercial variant of the iconic HK416, updated with the latest enhancements from HK-USA. Built with the same no-compromise commitment to performance and reliability that made the HK416 a legend, the MR556 A4 delivers exceptional durability, precision, and versatility in a civilian-legal configuration.

Featuring HK’s proven short-stroke gas piston operating system, the MR556 A4 keeps hot carbon fouling out of the receiver, ensuring cleaner operation, less wear on internal parts, and improved long-term reliability. An adjustable two-position gas regulator allows the user to fine-tune performance for both suppressed and unsuppressed use.

Fully ambidextrous controls make the MR556 A4 adaptable for any shooter, while its lighter weight and slimmer profile enhance maneuverability and ease of use in any environment. This rifle brings the legacy of the HK416 to civilian hands—refined, reliable, and ready for anything.
